1 Claim.

, The invention relates to improved apparatus for cutting or loosening the ring of material that builds up within cement kilns and has for its of time and chart. A H e I In the progress of .raw material through the kiln it changes from thegranular or pulverulent l" condition to the molten condition which it possesses when it leaves the kiln. In'the kiln the material passes through an intermediate state in which it is semi-molten and possesses viscous,

a ummy or sticky characteristics. In this state 15 it readily adheres to the lining of. the kiln and grows by accretion as the kiln rotates until itforms a dam or ring in thekiln which interferes withthe operation of the kiln by cutting down the amount of combustion gases passing through. Therefore it is necessary that the ring be removed periodically. The apparatus of the present invention accomplishes this removal efiiciently and with a minimum of time and efiort. With these and other objects in view themvention may consist of certain novel features of construction and operation, as will be more fully described and particularly pointed out in the specification, drawing and claim appended hereto.

In the drawing which illustrates an embodi- 30 ment of the invention and wherein like reference characters are used to designate like parts- Figure 1 is a side elevational view showing the improved apparatus of the present invention;

) Figure 2 is a vertical sectional view taken sub- 35 stantially along line 2-2 of Figure l and showing the rear of the feeder carriage;

Figure 3 is a vertical sectional view taken substantially along line 3--3 of Figure 1; and

Figure 4 is a fragmentary plan view taken sub- 40 stantially along line 4-4 of Figure 1.

Referring to the drawing, particularly Figure 1, the ring cutting machine of the invention is embodied in a portable carriage l0 consisting of a base H and uprights l2 which journal rollers i3 5 at their lower ends. The portable carriage is suitably anchored to the foundation M in the position desired by the rods l5 secured at their upper ends to the uprights l2 and at their lower end to the foundation by means of eye bolts H5.

50 The tool for actually cutting the rings of builtup material from the kiln consists of the plunger l8 having a suitably shaped forward end to adapt the plunger for the purposes described and which is mounted for axial reciprocation within open- 55 ings l9 formed in the uprights l2 respectively.

When the forward end of the plunger I8 is lengthened materially it is found desirable to counterbalance the rear end of the plunger by the addition thereto of the portion 20 which at its extreme rear end carries a counterbalancing 5 weight 2|. For reasons to be presently described it is necessary to prevent the plunger ill from rotating and for this purpose a member 22 is suitably fixed at its ends as at 23 to the plunger. Said member has engagement with the rear upright l2 so that said member forms a key with respect to said upright, preventing rotation of the plunger although permitting axial reciprocation of said plunger.

The mechanism for causing reciprocation of the plunger, whereby forward movement of the same will constitute a cutting stroke is driven by an electric motor 24 suitably supported upon the base ll of the carriage. Said motor drives a reducer 25 which is operatively connected by means of the belt 26 with a sprocket wheel 21. A similar sprocket wheel 28 is mounted at the forward end of the carriage, the said sprocket wheels receiving the endless chain 30 which is thus driven by the electric motor 24 through the instrumentality of'the reducer 25 and belt 26. The chain shown in Figure 4 consists of rollers 3! and connecting links 32. At least one lug 33 is suitably fixed to said chain, the function of which will be presently described. Said lug may have a shape such as shown in Figure 3. During horizontal movement of the upper portion of the chain and while the chain is travelling from sprocket 28 to sprocket 21 the same is supported by the bracket 34 suitably supported at its ends by the up- 35 rights l2.

The feeder carriage supported by the forward upright l2 consists of forward and rearward plate members 35 and 36, said members being joined by the carriage bolts 31 and 38. These carriage bolts are freely supported by the forward upright l2 and thus movement of said feeder carriage with respect to the upright is possible. Guide rods 39 are provided for the feeder, said rods being suitably secured at their rear end to the rear upright l2 and extending for some distance beyond the forward upright.

At a point substantially intermediate the uprights l2 a collar 40 is fixedly secured to the plunger l8. Each side of the collar is connected to the plate member 35 by means of a flexible chain 4! having interposed between its ends the coil spring 42. It will therefore be seen that when said plunger is moved rearwardly energy will be stored in said coil springs 42 so that upon 2 2,176,238 r .7 release the plunger w l prin f rwardly o ac- A pl rali y of lugs may be applied to said chain lease the said plunger from the action of the lug ment with the rear upright l2.
